)ly invention lurtiler consists ill tile llleaila l'or ettiecting tilese results, for Securinn` regulated speed of circulation, and it also includes tlle construction of tile apparatus. a5 nlore particularliy pointed out in tile elailllS.

In tlle accompanying dra\\f'ings-ll`igure l is a longitudinal vertical Section ot' nly apparatus on 'the lille l, l, of Fig. 2. Fig. 2 is a 'transverse rertl/ea/Lsectl'on on tile line 0 9 of Fig. i. F ig. 3 is a perspective view of 'plan andhorizontal section on the lines Ll,

' movable cover made in sections. In the up- `members G, the quadrangular intervening walls 'downwardly inclined, so that it is of atvthe top. On the bottom of the can are placed in two rows, as shown in Fig. 2 and posed in the upper part of the tank A beone of the freezing cans. F iguty is a partial a, o, b, c, and c, 4, of Fig. l.

Similar numbers and letters of reference indicate like parts. A is a tank having inner walls B and outer walls C, with an intervening packing of heat insulating material D. 1Q is a reper part of the tank is a. frame formed of longltudinal members F and transverse spaces being of sufficient size to permit the introduction into the tank, through each space, of a freezing can H. Said cans when in place, rest on the bottom of the tank and are thus immersed in the refrigerating liquid'which is supplied to said tank in the manner hereinafter to be described.

Each freezingcan H, as shown in Fig. 3, is a vessel of sheet metal preferably having its less cross sectional area at the bottom than two supporting flanges 5 which rest on the bottom of the t-ank, so that a space is formed beneath said can. Within the can and rising upwardly from the bottom is a hollow projection 6, open at its lower end. 7 is a U-shaped pipe,.one leg'of which extends through the opening at the bottom of the projection and upwardly into .said projection, while the other leg extendsupwardly on the outside of the can,v the intermediate portion passing below the bottom of the can and through one of the supporting flanges 5, said pipe being secured to the can in any suitable way. At -the upper extremity of the pipe 7 is a return bend 8, which extends downward for a short dis-tance below the liquid level in the-tank. The cans H are so 'that the bent overfends 8 ofsaid pipes 7 will all enter a trough If which extends longitudinally across the tank. Said trough is closed-at its ends and is preferably hung by straps J from a longitudinal member F of the grid.

Communicating with one end of the trough I is a pip'e Kvleading to the suction end of a pump L, which pump delivers by pipe 'M into a cpoler N for the refrigerating liquid. This-cooler may be of any suitable construction andconnectedwith any refrigerating machine. From the cooler extends a pipe communicatping'with a transverse header l above the tank A, and from this header extend vertical pipes Q communicating with the longitudinal pipes R, S, which are distween the cans and the pipeA walls. The pipes R, S, are preferably hung in straps T from the outer longitudinal members F of liquid to vrise therein.

downwardly from the header l), and com-r municates with another longitudinal pipe V which is supported below the trough I by the straps J, which straps also support said trough.

The operation is as follows: The refrigerating liquid is caused to circulate through the cooler l by means of the pump L, and is delivered into the tank through the perforated pipes ,lt,'&l, V, the openings in the wall of which pi pes being preferably provided with short tubular extensions lV. Said liquid then passes upwardly in the can projections'G to the top thereof, and then by the pipes 7 is delivered into the trough I, whence it discharges by pipe l( tothe suction end of puinp L, whereby it is again forced through the cooler N and returned to the tank.' The lpipes 7 serve first, to free the can projections t5 from air, thus allowing the refrigerating The surfaces of said projections t) then become freezing surfaces,

that, by reason of their proximity to the can surfaces, already stated, the distance through which the ice is frozen is less than half that existing between the freezing surfaces of the standard can, and the freezing time' is reduced from about 70 hours to about 16 hours. Second, to cause a'circulation of th:l refrigerating liquid through said projection. To this end theV return bend'8 is extended downward below the level of the refrigerating liquid in the tank, so that a siphon action is produced, whereby the liquid is drawn from the projection 6 into the trough I whence, as already described, it is removed Irv-the pump L, and returned to the tank. By raising or lowering the liquid level in the trough I, a slow or rapid circulation of the liquid may be established, each siphon passingthe same quantity of liquid. This raising'or lowering of said liquid level may be regulated by means of the valve X irr discharge pipe K, or by varying 'the speed of pump L. lt is preferable that the top edges of the trough l should be only slight-ly abovethe liquid level in the tank; and, of course,

the trough should be deep enough to acconimodate the siphons. The act of quickly lowering the can into the tank is sufficient to cause its siphon to flow, as the refrigerate ing liquid will enter the pipes 7 after the air has left with sufficient force to rise over the edge of the trough and start downward tiow into the same. But obviously, any suitable extraneous means for starting said flow may be used. v

It will be observed from Fig. 3 that the can H with its pipe 7 forms a structure com-- plete in itself, and easily introduced or removed from the tank without separating the' pipe from the can. A lso that said projection decreases in cross .se/.tional area from bottom to Atopv while the can similarly dethe frame. A third vertical pipe'U extends creases from top tobottom. Also from Fig.

all of the opposing faces of the ice layers formed on said Surfaces may be caused simultaneously to meet during the freezing operation, and to unite to form a single Solid ice cake. 'ln another application for Letters Patent Serial No, 448,919, tiled sin'iultaneously herewith. l'have claimed the process of making can ice which consists in freezing water between the outer surface of an inter nally refrigerated chamber and the inner surface of an externally refrigerated casing inclosing said'chamber, the distance between said Surfaces, measured in any given cross sectional plane parallel to the lbottom of the casing, being everywhere the same, and continuingi` the operation until all the opposing faces of the ice layers formed on said Surfaces simultaneously meet and unite to form a single ice cake.
